12th Ave NW Basin Drainage Improvement Project Update
Project Update, March 2022 from Seattle Public Utilities
Last year, we reached out to the community with an update on the 12th Ave NW Basin Drainage Improvement project. While the natural drainage systems element of the project is still being designed and construction has been rescheduled, we are excited to share that the design phase is complete for the underground detention pipe and conveyance project elements. Next steps for this portion of the project are awarding a contractor and onboarding a construction team in the coming months. Construction is expected to start as soon as late May 2022.
The underground detention pipe and conveyance elements of the project are located mostly along 10th Ave NW and 11th Ave NW between NW 120th and NW 125th streets and along NW 125th St to 6th Ave NW (see map below). Once we have more details about anticipated construction sequence, staging areas, impacts, and schedule, we will share those with the impacted community members.
spupLooking Ahead
If you live along the side of the streets shown in the work area (see map) and have private encroachments in the right of way, like a planter, retaining system, or bollards, you may need to remove them prior to construction.
Additionally, if you have an improvement on the property line, like a fence, we may need to work with you to temporarily re-locate it during construction. If you are unsure about the property line location or whether you have encroachment in the work area, please reach out to the project manager, Sierra Gawlowski, at Sierra.Gawlowski@seattle.gov.
Direct replies to GovDelivery email messages will not be received by the project team. As always, if you have a question about the project, plea
Best,
